[Asterisk-Users] Diax echo problem

[Dan]

Hi Fletcher,

>Good morning,
>    I just got asterisk up and going and set it up to communicate to test

>
>My Diax client --> IAX2 on my asterisk server --> IAX2 (voice pulse 
>server) --> PSTN -->my PSTN phone.
>
>I don't have any ZAP hardware. I'm only communicating using IP.
>For timing, I installed the ztdummy module successfully and execute modprob 
>ztdummy prior to starting up asterisk.
>I use an Intel router to go from my asterisk server to the voice pulse 
>asterisk server.

>Here is what happens:

>(1) The person on my PSTN phone talks and always hears an echo of what they 
>said.
>(2) Using the headset on my Diax client, I can hear the person on my PSTN 
>phone clearly, I don't hear an echo on the ear phone.
>(3) When I talk talk into the headset microphone, the person on my PSTN 
>phone can not hear me at all. Also, I don't hear any sound in my ear phone. 
>It >sounds totally dead.

Check that the mic is selected as record device and wave as playback device.
Check that wave is unselected as rec device and mic unselected as playback 
device.

Best regards,
